In order to prevent out-of-plane buckling of buckling-restrained brace, its connections must have enough out-of-plane stiffness and be kept elastic. This paper deals with out-of-plane stiffness and yield strength of buckling-restrained brace's connection whose section is cruciform. Firstly, methods of calculating both out-of-plane stiffness and yield strength of connection are proposed by means of RBSM. And secondly, experimental verifications to load connection specimens were conducted. As a result, it is clarified that out-of-plane stiffness is very small if finstiffener is not connected to beam-flange. Therefore, it is recommended that fin-stiffener should be welded to beam-flange to satisfy required out-of-plane stiffness and yield strength.
